The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
This one's stunned or freshly dead in the pictures, because the water in my photographing tank was a bit too warm for him after being under the bright light for a while.
This mayfly was collected from the Namekagon River in Wisconsin on January 31st, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
